SAN SALVADOR, El Salvador (AP) — Thousands of war veterans in El Salvador are demanding that authorities release 95 of their fellow veterans detained during a protest this week to demand a monthly pension.

The former soldiers and ex-guerrillas marched throughout the country on Thursday, a day after the group was detained while blocking several major highways.

The protesters were demanding lawmakers pass a bill that asks that all those who fought in El Salvador’s 12-year civil war receive a pension and other benefits.

Authorities say the veterans are accused of disorderly conduct and of resisting detention. They say one of them will be charged with terrorism because he threw a makeshift explosive device that injured several police officers.

The veterans vowed to continue their protesting until their demands are met.
